After dating for years, Vanderpump Rules sweethearts Tom Schwartz, 33, and Katie Maloney, 30, finally got engaged in July, and now they reveal to In Touch secrets about their big day, including who will make the guest list.

Neither James Kennedy nor Lala Kent should expect to make the final cut. Tom says, “James is too loud and a liability — I think even he would acknowledge that!”

As for Lala? “Absolutely not!” says Katie.

Katie and Kristen Doute’s friendship has definitely had its ups and downs, but “regardless of whether Kristen makes the cut or not, she’s going to show up anyway,” Tom jokes of the infamous party crasher. “So we might as well just invite her!”

Tom and Katie say their boss, Lisa Vanderpump, will also be in attendance. “She offered to officiate, which would be really special,” Katie reveals.
